Job Title:
Postdoctoral Scholar

Department:
Arts and Sciences | Physics Administration

The National Extreme Ultrafast Science Facility (NeXUS) is a new user facility under development at The Ohio State University. It is designed to enable novel materials and chemical dynamics studies. It will include an ultrafast laser that delivers a kilowatt of power at up to a 100 kHz repetition rate.  This project will be the first to bring this recently developed technology in high average power, ultrafast lasers to the United States.  This laser will be used to produce Extreme Ultraviolet (XUV) and soft X-ray pulses by high harmonic generation.  NeXUS is also developing four end stations to enable time resolved experiments using XAS/XRS, STM, ARPES, LIED, and XMCD measurements. These end stations and ultrafast pulses of XUV light will enable researchers to study how electrons move in molecules and materials at time scales as fast as attoseconds and length scales as small as angstroms ( https://nsf-nexus.osu.edu/ ).

The individual in this position will be essential to the development phases of the facility: design, assembly, verification experiments, and validation experiments.

Under the supervision of Professor Louis DiMauro, he/she, in conjunction with the NEXUS team and Physics administration, will work on two main activities:

1) Commissioning of the time-resolved attosecond and laser-induced electron diffraction (TR-LIED/ATTO) end station at NeXUS. The LIED mode of operation will provide precise spatial-temporal probing of molecular dynamics, creating molecular movies with sub-femtosecond time resolution and sub-angstrom spatial resolution. The ATTO mode of operation will probe electron dynamics using photoionization attosecond metrology. The postdoc will work on integrating the various commercial and custom components to bring this new state-of-the-art instrument online.

2) Conducting first TR-LIED/ATTO experiments at NeXUS, in collaboration with NeXUS PIs and first users. The postdoc will design and execute verification and validation experiments that demonstrate the capabilities of the NeXUS system. The postdoc will work with teams of international researchers to design, execute, and analyze their proposed experiments.

In addition to these two primary activities, the postdoc can also participate in other NeXUS activities, such as experiments on adjacent beamlines.
